Mobile App Development Timeline: How Long Does It Take?
Updated on 27 August 2026 2 min read
Mobile app development timelines vary depending on complexity. An overview of the steps and their typical duration.
Mobile app development timeline is a key question for planning a launch, especially when the schedule is tied to a commercial event or a fundraising round.
The main steps of a mobile project
A mobile development project generally goes through several phases: defining the need and priority features, designing the mockups (UI/UX), development, testing on different devices, then submission and review by the stores. This last step, often underestimated, can add several days or even weeks to the schedule, especially on the App Store, whose review process is stricter than Google Play's.
Timelines that depend heavily on complexity
A simple app with a handful of screens and little business logic can be built in a few months. A richer app, with authentication, payment, push notifications, and back-end syncing, generally takes longer. The choice between native and cross-platform development also affects duration: building two separate native apps (iOS and Android) generally takes longer than a single cross-platform codebase.
Factors that extend the schedule
- The number of rounds of feedback on the interface design
- The complexity of third-party integrations (payment, geolocation, notifications)
- Review time on the App Store and Google Play Store
- Availability of content and visuals provided by the client
For a realistic schedule, it's recommended to start with an MVP (minimum viable product) focused on essential features, rather than trying to build every planned feature in the first version.
